Pigs have the highest rate of chromosome abnormalities among domestic animals. The most frequently observed abnormality is a chromosome rearrangement known as reciprocal translocation which can be diagnosed by karyotyping. The incidence of translocations among breeding boars ranges from 0.5% to 1.5%. Carriers of translocations have litters with 3-5 piglets less than herd average. Testing boars before breeding and eliminating carries has been shown to reduce the incidence in the herd and provide an economic return on investing in testing of about 5:1.
